Anthraquinone colorants containing copolymerizable vinyl groups |
(57) Disclosed are thermally-stable, red, anthraquinone colorants which contain one or
more ethylenically-unsaturated, photopolymerizable radicals and which may be copolymerized
with ethylenically-unsaturated monomers to produce colored compositions such as colored
acrylic polymers, colored polystyrenes, and similar colored polymeric materials derived
from other ethylenically-unsaturated monomers. The compounds possess good stability
to ultraviolet light, good solubility in vinyl monomers, good color strength and thermal
stability. Also disclosed are acrylic polymeric materials, i.e., polymers derived
from acrylic acid esters, methacrylic acid esters and/or other copolymerizable vinyl
compounds, having copolymerized therein one or more of the colorant compounds of the
present invention.
